Apparatus and system for acquiring seismic data over a loose surface

A system for performing seismic exploration over a loose surface, the system comprising:

• at least one apparatus for acquiring seismic data over the loose surface, wherein each apparatus of the at least one apparatus comprises:
• a housing capable of moving on the loose surface, wherein the housing has an opening configured at a bottom surface of the housing;
• a seismic sensing unit configured within the housing at an angle with respect to a horizontal plane,
• wherein the seismic sensing unit is operable to retractably move towards and away from the opening within the housing, whereby in response to moving towards the opening, the seismic sensing unit establishes contact with the loose surface for acquiring the seismic data;
• a connecting member connected to each apparatus of the at least one apparatus, wherein the connecting member is pulled to move the at least one apparatus over the loose surface to perform seismic exploration;
• a supporting unit removably attached to the bottom portion of the housing, the supporting unit having the seismic sensing unit mounted thereon;
• and
• a drive channel configured on the supporting unit, wherein the seismic sensing unit is movably mounted on the drive channel for facilitating the retractable movement of the seismic sensing unit.
